How do I install "z" script?
In the z readme after line 48, it says:
Installation:
Put something like this in your $HOME/.bashrc or $HOME/.zshrc:
. /path/to/z.shcd around for a while to build up the db.
You need to download the z.sh file to a directory of your choosing, then tell your .bashrc where it is, so your terminal can find it. (The same applies for z-shell, which is just another shell system.) Then, after you use bash for a while, z will know your favorite locations.
You can download and add to *rc files using command line as so
# Download to latest to home dir
wget https://raw.githubusercontent.com/rupa/z/master/z.sh -O ~/z.sh
# Add to .bashrc
echo . /path/to/z.sh >> ~/.bashrc
# Add to .zshrc
echo . /path/to/z.sh >> ~/.zshrc
